Someone has made an example here where the following custom functions are available for cut & paste use:

• getElementById()
• getElementsByClassName()
• getElementsByTagName()

Then you can do something like this

function doGet() {
  var html = UrlFetchApp.fetch('http://en.wikipedia.org/wiki/Document_Object_Model').getContentText();
  var doc = XmlService.parse(html);
  var html = doc.getRootElement();
  var menu = getElementsByClassName(html, 'menu-classname')[0];
  return menu;
}
